Question

prove the following 1. the sum of the exterior angles of the parallelogram so formed is 360 degree​

Answer 1

Step-by-step explanation:

The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon.

Answer 2

Answer:

generally  sum of all outer angles of any polygon is 360

      also the sum of all interior angles of parallelogram is

                     = 180(n-2) n is no of sides

                     = 180 (4-2)

                           =  360

     so each interior angles will have 360 / 4

                           = 90

and interior angles and exterior angles form linear angle

                180= exterior angle+ interior angle

                 180 =  x + 90

            180 - 90 = x

                    90 = x

            so all other exterior angle will 90

                   90 * 4 = 360

             so hence it is proove
